The best way is with a blade sharpener like bradley. http://i24.ebayimg.com/04/i/001/10/dd/9aa0_12.JPG

The best cheap way is a bench grinder.

The worst cheap way is with a angle grinder.

The cheapest way is with a file.

How often to sharpen depends on types of grass if your dinging them and what not. Some do it daily, I aim for every 25-30 hours.

MY OPINION is the bench grinder is the worst
An angle grinder if you know how to use it properly the best at home.
I personally take mine to the shopand have then sharpened only 10 bucks for three blades is not a bad price.

How often? As often as needed to keep from tearing the grass.
I do mine weekly.

I use a Magna Matic blade sharpener. They are expensive but they are the best if you have a lot of blades to sharpen, it pays for itself just by the time it saves.

i bought the bradley blade sharpener and it doesn't work very well for commercial blades that are sharpened almost to the middle. I went back to my angle grinder with the 40 grit flap disc. it gets them much sharper and doesn't get them nearly as hot as a normal grinder disc does.

Thanks all for your replies, seems everyone has different opinions on this subject. Every method has pros and cons depending on your blade design. The angle grinder seems the fastest but very inconsistent as far a nice straight edge. I even seen blades sharpened right on the mower. Iam sure those blades are not balanced.

Those Bradley's seems nice if your blades are straight and flat. Mulching blades are far from that.

bench grinders can do a lovely job if you take your time and don't apply too much pressure.

However most people go "ohh a big grinder lets SHOVE steel into it so it works faster"

I always finish the job with a hand file too, it cleans off any burrs left by the grinder and creates a very fine blade finish.

I take mine in most of the time. Any suggestions on balancing the blades once you have sharped them?

Here are a couple of the blade balancers out there.
